We examine the binding energies of massive stripped-envelope core collapse supernova (SECCSN) progenitors with the stellar evolution code MESA, and find that the jittering jets explosion mechanism is preferred for explosions where carbon-oxygen cores with masses of ${\gtrsim} 20 \, \mathrm{M}_\odot$ collapse to leave a neutron star (NS) remnant. We calculate the binding energy at core collapse under the assumption that the remnant is an NS. Namely, stellar gas above mass coordinate of ${\simeq} 1.5\text{{--}}2.5 \, \mathrm{M}_\odot$ is ejected in the explosion. We find that the typical binding energy of the ejecta of stripped-envelope (SE) progenitors with carbon-oxygen core masses of $M_{\rm CO} \gtrsim 20 \, \mathrm{M}_\odot$ is $E_{\rm bind} \gtrsim 2 \times 10^{51} {~\rm erg}$. We claim that jets are most likely to explode such cores as jet-driven explosion mechanisms can supply high energies to the explosion. We apply our results to SN 2020qlb, which is an SECCSN with a claimed core mass of ${\simeq} 30\!-\!50 \, \mathrm{M}_\odot$, and conclude that the jittering jets explosion mechanism best accounts for such an explosion that leaves an NS.
